	// Looking for a ul element that matches the path of the current page in order to expand it
	// CSS ref might look like: body#issues .SideNav .subnav .issues_subnav .issues_awards_and_recognition_level2
	// Process works something like this
	// 1. Navigation is created by user
	// 2. Templating adds a classname to each UL element that matches name entered by user
	//		"Awards and Recognition" inside "Issues" becomes ".issues_awards_and_recognition_level2"
	//		The characters " " and "-" are converted to underscores
	//		and the characters ",'\"" are deleted
	// 3. Appropriate navigation element is included in an HTML page when it is generated
	// 4. This function is called onload, using behavior.js addLoadEvent, 
	//      compares path and classes using behaviour.js getElementsBySelector and expands the  UL that matches
